10/19. 40/4=10, and 56/4=19. therefore the answer is 10/19.
Answer:
"perpendicular"
Step-by-step explanation:
We need to find slope (m) of both line JK and LM
Slope has formula:

Lets find slope of JK:

Lets find slope of LM:

we know if we multiply two lines' slope and get -1, they are perpendicular. Let's check:

Hence, they are perpendicular
I think the answer would be 41.28
Answer:
yep It's 40 :)
Step-by-step explanation:
because whenever you multiply two negative numbers it will come out as a positive number.
